In an oil orlother 'uidfcoolerlnor heatv exv 'changera ofthe tubular removable tulie'fy bundle type, thecombination of.fha1fcylindrical shell segments having marginal fabutting f iianges of Whichthe roots are spaced respectively inside and outside of the longitudinaledgesof the segments to provide` a longitudinal lap, 'half ,ring-vsegments secured at the ends of the flanges and to the adjacentendsurfacs of the shellsegmentsand-of which two -aie 'channelledyfon-the ,reception of Y packing, packing in-.said channelledrin'g'isegments a packingringV secured tothe face of the channelledring-- segments; a .tube bundle having tube sheetsY of whichoner isfixed-to thefsegments constituting one ring and is groovedfor-thereception of the. endsof the `shell. segments, andY of it isl well tostate 'thatrthe which the other is movable in the shell and is packed bysaid packing, yheads-respectively bolted to one of the tube sheets andto one pairV of half rings, and pipe't'tings confined to one of theshell sections. Y

2. In an oil or other fluid cooler or heat exchanger ofthe tubularremovable tube bundle type, the combination of VVa longitudinally splitCooler shell provided at one end with the half `segments of a ring, atube bundle having a floating tube sheet, and a packing external of thesegments. h f

3. In an foil or other fluid cooleror heat exfloatingv tube sheet andinside of said half ring chang'er ofthe tubularl removable tube bundletype, fthe -C Qmbination of a longitudinally split cooler shell Ahavingoutward flanges at its edges havingnanged'edges detachablyconnectedtogetherand of'y which oneshell segment is xedly supported andis providedY with pipe connections andof which the other shell segmentAis removablev and devoid ofpipe connections, and a tube bundle mountedinthe shell.V

5. Injapparatus of thetype specied the combination of a longitudinallysplit cylindrical shell i having anged edges detachably connected Y'tonvgether and `of which one shell segment is xedly supporteda'nd isprovided with pipe `connections and of` Whichtheuother shell segment isremovable ,ianddevoid of pipe connections, a tube bun- "dle, mountedrinthe shell,`and eyesA at the end parts of the removable shellvv segmentfork attachment to, cables into the'bights of i which the shell sectionkcan be`rolled to aiord access to the tube bundle withoutbreakingthepipe connections."

. 6.'V In apparatusfof the type specified the `combination of alongitudinally split cylindrical shell l having flanged edgesdetachably'connected togethervand ofA which one shell segment is ixedly supportedand isfprovidedvwith'pipe connections vandof Vwhich the other Yshellsegment is removable and devoid of pipe connections, a tube bundle.mounted inthe shell, andV gussets' arranged `between the flanges andshell segments and of lWhich those at Ithev ends of .the removable shellsegmentsxare providedwith rings.

Y 7. In apparatus ofthe typespecifed the comlbinationVof'semi-cylindrical shell sections each having.V marginal flanges,segmental end rings secureat the ends of the flanges fand to theadjacentsurfaces of the'shellV sections and of which one is a packing ring,gussets secured tothe flanges and to the surfaceofrthe shell sections, atube ,bundle having tubesheets of which one is fixed to one-ofV said endrings,`and of which theV other ismovablesand extractable from the shelland is packedbysaid packing.ring, and headsof which one is nbolted toone of said Yrings and o f which the otherjis boltedto the free tubesheet.
